Table 2.
2-cell embryo 2n/4n mosaicism rate (%) | 5- to 8-cell embryo 2n/4n mosiacism rate (%) | |
---|---|---|
In-vivo matured oocytes | 1.0 (2/199)* | 10.2 (19/187)* |
In-vitro matured oocytes | 0.9 (2/224)** | 5.9 (6/102)** |
Mosaicism rates were compared between the in-vivo and in-vitro matured oocyte group using χ2 analysis and between embryo stages in each group. While no significant difference was detected between oocyte maturation groups, there was a significant increase in five- to eight-cell mosaicism rates compared with that observed in two-cell embryos
